    Can we create graphene material using silvaco tcad tools

    Generally its not possible without physical models included in library. But you can try do define new material with corresponding models (mobility, scattering, etc.) At least it was done for Silicon Nanowire Solar Cell - https://www.azonano.com/news.aspx?newsID=26300

    Metal Density in Layoput

    Metal etching speed depends on how much surface covered. To stay within acceptable etch tolerance is better to have certain metal density.

    Do UV power LEDs come in different forward voltage groups?

    Forward voltage Vf is internal property of p-n junction and depends from energy band structure.

    SILVACO Atlas, PIN photodetector simulation problem

    Hi HalexHarter, Your beam statement is OK, but it shall be aligned with your PIN diode structure. Top metal layer is considered as non-transparent in Silvaco simulation.

    TCAD photodiode (iv characteristics by using atlas) SILVACO TCAD

    Hi idayasin, Your carrier lifetime setup is looking very weird: TAUN0=0.2 us TAUP0=10 us For photodiodes general values are: TAUN0=50E-6 TAUP0=50E-6
